# Sample flows
The examples in this section show how to sequence templates from the Android for
Cars App Library to create flows for common app tasks.
Many of these sample flows end with the
[Navigation template](https://developers.google.com/cars/design/create-apps/apps-for-drivers/templates/navigation-template),
which is only available for navigation apps. Other apps can use versions of
these flows by switching to a navigation app as the last step in the flow. For
examples, see
[Access location details and start navigation](https://developers.google.com/cars/design/create-apps/sample-flows/access-location-and-navigate) and
[Purchase using existing payment method](https://developers.google.com/cars/design/create-apps/sample-flows/purchase-with-existing-method).
Each flow includes details about how the step counter is incremented. For
context, see
[Step counts and refreshes](https://developers.google.com/cars/design/create-apps/apps-for-drivers/plan-task-flows#steps-refreshes).
> [!NOTE]
> **Note:** Most template sequences are the same for both Android Auto and AAOS. However, permission template sequences differ: Android Auto permissions are on the phone, while AAOS permissions are in the car.
